Help! this evening I applied the latest security patch from Apple for Safari, and restarted my iMac. Now, all the desktop icons have very fuzzy / blurred / bleeding text. I tried re-logging in, restarting, even tried changing the font-smoothing style, to no avail. Can anybody help? I am attaching a part of a screenshot of the desktop. Funny, that no other text inside browsers / editors seems affected, and even icons in other Finder windows are normal. And when i login with a different user, the desktop is perfectly fine there!
